Abstract: The goal of this presentation is to describe new concepts for Internet next generation : The Virtual Internet. This architecture is based on virtual networking with a piloting system able to optimise 1) the placement of virtual resources of a new virtual network, and 2) the urbanisation of virtual resource implemented on physical network equipment. This architecture deals with mechanisms capable of controlling automatically the placement of all virtual resources within the physical network.
In this presentation, we will describe how to create and delete virtual networks on the fly. Indeed, the system is able to create any new network with any kind of resource (e.g., virtual switch, virtual routers, virtual LSRs, virtual optical path, virtual firewall, virtual SIP-based servers, virtual devices, virtual servers, virtual access point, and so on). We will show how this architecture is compatible with new advances in High-Capacity Optical Networks, SDN (Software Defined Networking) and Open Flow approaches, and 4G networks.

Abstract: Offloading is a promising technique to help network operators face the continuous growth of data traffic. It allows extending network capacity while avoiding expensive infrastructure upgrades. We advocate the use of a data shuttle service model to offload bulk transfers of delay-tolerant data from the Internet onto ordinary vehicles equipped with data storage capabilities. We will also discuss a specific challenge toward this goal, which is how to select of the most appropriate roads between data sources and destinations. This leads to a combinatorial problem that becomes stubborn when using raw road maps. We simplify this problem by first proposing an embedding algorithm that computes an offloading overlay on top of the road infrastructure. We evaluate our proposal using actual road traffic counts in France. Numerical results show that we can satisfy weekly aggregate requests in the petabyte range while achieving throughputs above 10 Gbps in the case of 20% market share and only one terabyte of storage per vehicle.

Abstract: Ad Hoc and Mesh networks face difficult environment to offer good communications. Indeed, interference, mobility and radio links provide often narrow bitrates and unstable links. In addition, devices are working on batteries and need to be low power. The talk introduces algorithms and mechanisms that offer stability and quality of service for ad hoc and mesh networks. Those algorithms are also low power with the function Start and Stop that turn off useless devices in the network. A demonstration of a Mesh Network with Raspberry PI embedded computers will be shown.

Abstract: The increasing importance of network virtualization in telecommunications is becoming tangible for the common Internet user. It is not hazardous to state that most of Internet servers accessed today are hosted as virtual machines. It is not even hazardous to state that in a very close future most of these virtual machines will be moving nodes across data centers, cities, countries and continents, to meet resiliency goals and increase users' Quality of Experience (QoE). In this talk, we will describe the novel network protocols supporting such an evolution of moving virtual machines, with a particular focus on recent propositions to augment user's QoE in Cloud access. We will describe two realistic solutions and the related proof-of-concept showing how service downtime during VM migrations on very long distances across Brazil, Europe and Asia can be made negligible, and how user's application throughput can be significantly augmented by means of incremental and inexpensive functionalities to the existing TCP/IP architecture.
